TAPE-FEEDING- DEVICE.

Specification of Letters Patent.

Patented May ;,1909.

Application filed September 22, 1908. Serial No. 454,160.

To all Q07! em if m (by concern:

Be it known that l, Josnrn A. Ponnnn, a l subject of the King of England, residing at il oonsocket, in the county of Providence and Eta e of lihode Island, have invented new and useful Improvements in Tapel eeding Devices, of which the following is a specification.

My invention pertains to paper box machinery and more particularly to means for feeding binding tape to paper boxes incidental to the manufacture of the same; and it contemplates the provision of a simple and inexpensive device which is adapted to feed binding tape step by step without liability of the tape sticking and causing waste thereof, and is also adapted to be quickly and easily cleared of collected paste, and is otherwise practically advantageous.

With the foregoing in view the invention will be fully understood from the following description and claims when the same are read in connection with the drawings, ac companying and forming part of this specification, in which:

Figure 1 is a side elevation of so much of a box making machine or apparatus as is necessary to illustrate the best practical embodiment of my invention of which I am cognizant. Fig. 2 is a transverse section, taken in the plane indicated by the line 22 of Fig. 1, looking in the direction indicated by arrow, and with the binding tape omitted.

Similar letters designate corresponding parts in both views of the drawings, referring to which:

A is a frame which may form part of or be suitably attached in a lined manner to the frame of a machine for making paper boxes.

B is a sub-frame, pivoted at (t to the frame A. so as to be capable of being raised and lowered, and C is a tractile spring connected to the frame A and detachably connected to a lateral projection b on the subframe B and having for its ollice to yieldingly hold the sul -frame down in the position illustrated and yet permit of said subi'rame being swung upwardly when necessity demands, as will be hereinafter pointed out.

On the frame A is a lateral journal c, and on said journal is removably arranged a wheel D having a perimeter of g -shape in cross-section, as best shown in Fig. 2, and

large wheel E having a circumferential groove ct which is of V-shape in cross-section to receive the perhpheral portion of the wheel D and is milled or provided on its walls with minute crosswise grooves e in order to enable it to take better hold of and positively feed the binding tape which is indicated by F in Fig. 1.

The comparatively large and oircumferentially grooved wheel E is loosely mounted on a journal f extending laterally from the sub-frame B, and is provided at one side with an annular flange 9. This flange g is for the engagement of the kerfed heads or portions 71 of dogs G, the inner ends of which are disposed in notches t provided in a vertically swinging body H loosely mounted on the journal f and retained against lateral displacement by a washer l and a nut J or other means suitable to the purpose. The said swinging body or piece ii is provided with three arms 7r Z and m; the arms 7c and Z being connected by coiled. springs K with apertured lugs n on the dogs G, and the arm an being connected to a rod L, which is de signed to derive a reciprocatory motion from a suitable working part (not shown) of a box-making machine. As clearly shown by dotted lines in Fig. 1., the notches 'i are respectively provided with a wall 1?, disposed. radially to the center of movement of the swinging body H.

At the left of the wheels D and E and the appurtenances thereof I prefer to arrange a spool P for the binding tape, and a tank It for water, the tank being arranged interme diate the spool and the wheels D and E, and being equipped with idler rollers S and with a drum T, the office of which latter is to take up water from the tank and apply the same to the gunnned side oi the tape. When, however, a tape that is not gummed is to be used, the drum T may be utilized to apply paste or gum to the tape, or in other words transfer paste or gum from the tank R to the tape incidental to the passage of the latter to the wheels D and E.

In the practical operation of my novel device it will be manifest that when the rod L is reciprocated, the swinging body H will be oscillated, and that on movement ofthe said parts in the directions indicated by arrows in Fig. 1, the walls i of the notches i will serve to engage the inner ends of the dogs G and bind the kerfed portions of the dogs against the annular flange 9 of the wheel E, with the result that the said wheel E will be turned through a part of a revolution in the said di- 3 within the scope of my invention as defined rection. On the succeeding movements of the rod L and swinging body H in the directions opposite to those indicated by the ar rows, the kerfed portions of the dogs G will slip over the flange g of wheel E without transmitting motion to said wheel. From this it will be understood that the wheel E is turned step by step in one direction only,

which is materially advantageous inasmuch as it assures properfeed of the binding tape and precludes sticking of the tape and the consequent loss of more or less of the same. The binding tape which is used to secure the corners of paper boxes passes in a flat state from the spool P and over the drum T, but during the feed of the said tape between the wheels D and E it is reduced to V-shape in cross-section so as to conformto the shape of the corners of the boX that is being made.

Because of the gummed side of the tape being presented to the wheel D gum collects on the said wheel. This makes it necessary to clean the said wheel D at intervals, and when the same is to be done the spring C is disconnected from the lateral projection l) of the sub-frame B and said frame B is swung upwardly so as to carry the wheel E out of engagement with the wheel D, whereupon the latter may be readily moved off of the journal 0.

It will be gathered from the foregoing that by virtue of the wheel E being considerably larger in diameter than the wheel D to which the gummed side of the tape is presented, the said wheel D is turned at a high rate of speed, and consequently the tape does not have time to adhere to the wheel D which obviously lessens the liability of the tape sticking in the device.

The construction herein illustrated and described constitutes the best practical embodiment of my invention of which I am cognizant, but it is obvious that in the future practice of the invention such changes or modifications may be made as fairly fall in the claims appended.

Having described my invention, what I claim and desire to secure by Letters-Patent, is:

1. In a tape feeding device, the combination of a frame, a wheel mounted on said frame, a sub-frame connected with the main frame and movable toward and from the said wheel, a wheel carried by the sub-frame and having an annular flange at one side, a spring connecting the first-named frame and the sub-frame and adapted to yieldingly hold the second-named wheel against the first-named wheel, a swinging body carried by the subframe and mounted alongside the secondnamed wheel and having three arms and also having notches, dogs having their inner ends disposed in said notches and also having kerfed portions for engaging the said flange, springs connecting the dogs and two of the arms of the swinging body, and a reciproeatery rod connected to the third arm of the swinging body.

2. In a tape feeding device, the combination of a frame having a lateral journal thereon, a wheel removably arranged on said journal and having a perimeter of \Ishape in cross-section, a sub-frame connected with the main frame and movable toward and from the said wheel, a wheel carried by the subframe an having a circumferential groove normally receiving the perimeter of the first named wheel, and a spring detachably connecting the first named or main frame and the sub-frame and adapted to yieldingly hold the second named wheel against the first named wheel.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit nesses.
